Growing Cape Gooseberry in Tharaka Nithi

Soil suitability analysis based on Tharaka Nithi's nutrient profile

Cape Gooseberry can be grown in Tharaka Nithi County, but the soil scores 53/100 and needs targeted management to reach full potential. At an average pH of 4.99 the soil is strongly acidic, below Cape Gooseberry's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.23 g/kg), phosphorus (19.6 mg/kg) and potassium (211 mg/kg) all meet Cape Gooseberry's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Cape Gooseberry, which favours loam. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Tharaka Nithi's 53/100 suitability a realistic target here is closer to 3,313 kg/acre (~KES 397,560/acre) unless the constraints above are addressed.
